You might also like to take a look at our more general weight loss calculator. You exercise moderately (3-5 days per week) The activity levels and their factors are as follows: Activity Level These estimates are simply computed by multiplying your BMR by the factor specific to an activity level.

The BMR calculator will then adjust your BMR by various factors to show estimates of the calories you burn a day based on your activity level. One of the useful properties of computing such an estimate of your BMR is that you can then use this to esitimate the calories you burn a day. The calculator will return an estimate of your BMR using both of these methods. Some studies have shown the equation by MD Miffin and ST St Jeor to be more accurate here, while the Harris Benedict equation was created in 1919 and has historical significance. Similarly to the above formula by MD Miffin and ST St Jeor, weight is in Kilograms, height is in centimeters and age is in years. s is a factor to adjust for gender and adopts the value +5 for males and -161 for females.Īs an alternative method of calculation, the Harris Benedict equations adopt separate equations for men and women as follows:īMR = (13.7516 x weight + 5.0033 x height – 6.755 x age + 66.473) kcal/dayīMR = (9.5634 x weight + 1.8496 x height – 4.6756 x age + 655.0955) kcal/day

Here, weight is in Kilograms, height is in centimeters and age is in years. The equation introduced by MD Miffin and ST St Jeor is as follows:īMR = (9.99 x weight + 6.25 x height – 4.92 x age + s ) kcal/day These equations allow an approximation of your BMR to be computed from the above data. There are various methods to calculate an estimate of your BMR and the calculator will return two estimates based on the formulas developed by MD Mifflin and ST St Jeor as well as the Harris-Benedict equation. You are basically looking at the calories you burn a day when at rest with no digestion occurring. “the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state (meaning that the digestive system is inactive, which requires about twelve hours of fasting in humans)” Your Basal Metabolic Rate is defined on Wikipedia as: The calculator will then calculate an estimate of your BMR and adjust you BMR by various factors to allow you to see an estimate of the calories you burn a day based on your level of activity. To use the calculator, simply input details about yourself such as you age, gender, weight and height. More information about AMR can be found here.The BMR calculator allows you to calculate your Basal Metabolic Rate (BMR) as well as other information relating to the calories you burn a day. If you are an active athlete, use the AMR calculator. If you go to workout on some days, you can add AMR for those days. If you do simple office work or work from home, in many cases you have very little energy expenditure and therefore BMR is enough for the conversion.ĪMR is the BMR calculated by your daily physical activity. If you include regular sports activity in your life, count your calories consumed through AMR calculator.īMR is just the sum of the basic energy needed to run your body without any other physical or mental activity. If you want to avoid fat storage it is good to have a sports activity. The higher the calorie intake, the more fat is stored. The composition of the diet is not just about calories, but also about the individual ratios between fats, sugars and proteins. CAUTION - It is always a good idea to consult a nutritionist. Increase your daily calorie intake if you want to gain. The calculation is simple - if you give your body less calories, you will lose weight, if you gain more. (If you are doing a sport activity, you have a physically demanding job, use the AMR calculator.) With BMR data, you can gain control over your own weight. Why is good for you to know the value of BMR? If the same amount of energy was received by someone with a lower BMR value, energy would be stored in their fat stores.īMR decreases in older people. This is very common in athletes who have more muscle. It is influenced by factors such as:Īs the MBR rises, so does the body's need to absorb more energy. The MBR value is different for each person. Imagine not moving all day, just lying in bed, not eating, but just concentrating on breathing. So it is the amount of energy that your body spends only on basic functioning. Energy expenditure in this state is the sum of energy for vital organs (heart, lungs, stomach, brain, nervous system.

BMR is the amount of energy released at rest at neutral temperature.
